Answer:

22.3 km²

Step-by-step explanation:

The formula for the area of a circle is

A = πr²

r = ½d, so

A = π(½d)² =  ¼πd²

A = ¼ × π × (16/3)² = ¼ × π × 256/9  ≈ 22.3 km²

Divide the number 480 in a ratio of 3:5
Schach [20]

If it is a ratio of 3:5 you are dividing 480 into 8 parts (3+5).


So divide 480 by 8: 480/8 = 60


Then the ratio is (3x60):(5x60) or 180:300


To check it is correct, add up the two parts to see that they come to 480:


180+300 = 480. All good.


Hope this helps

How do you solve this?
Novay_Z [31]

Let's solve your equation step-by-step.


−7x=−2x2+15


Step 1: Subtract -2x^2+15 from both sides.


−7x−(−2x2+15)=−2x2+15−(−2x2+15)


2x2−7x−15=0


Step 2: Factor left side of equation.


(2x+3)(x−5)=0


Step 3: Set factors equal to 0.


2x+3=0 or x−5=0


x=  \frac{-3}{2} or x=5

Answer:


x=    \frac{-3}{2} or x=5


Hope this helps
